Does Sjögren's syndrome cause PBC, and what other symptoms does it cause?
Sjögren's syndrome doesn't cause PBC. Both are autoimmune conditions that often occur together, but researchers don't know if one causes the other or if they share underlying factors.
Between 40% and 65% of people with PBC also have Sjögren's syndrome. Sometimes Sjögren's symptoms like dry mouth and dry eyes appear before a PBC diagnosis.
There may be a genetic link between these conditions, as many autoimmune diseases involve similar gene changes affecting the immune system.
Regarding your other symptoms, it's important to discuss postnasal drip, asthma, low sodium, and concerns about acid balance (RTA) with your doctor. While Sjögren's can affect multiple body systems, these specific symptoms need proper medical evaluation to determine their cause and appropriate treatment.
